Hi there. I'm looking for information on speech recognition chips. Could any of you give me some pointers on references ? In particular, one question has been interesting me : How do s.r chips react to voice in an environment with background noise, for example an office with other people talking. Can a typical chip recognise its programmed keywords from among the extraneous voices ? Thanks in advance. Regards, bjh, University College Dublin "There's no future in time travel"

A couple of years ago BYTE Magazine (when it was still usefull) had an article or two by Steve Ciarcia on a speech recognition system based on a chip made by General Instruments (I think). It was called something like SP256. The interesting thing about this chip is that it is advertised as being a speech synthesis chip. Need more? Throw some e-mail at me.

The chip you're thinking of is the General Instruments SP-1000, which does LPC (linear predictive coding) analyis and synthesis. GI had application notes for speech recognition. The LPC filter they used was configured differently for analysis than for synthesis, so you can't use the chip to record then play back a sound. It seemed somewhat brain-dead to me. It had the advantage of being cheap enough to put in consumer products, although I'm not sure that anyone ever did so. The BYTE article described a board for the Apple II which used this chip. The board was available from MicroMint (sp?). If anyone wants some of these chips, I've got some I could sell. It probably makes more sense to use a DSP chip for speech recognition now. Motorola has some LPC software on their bulletin board. -- Eric L.

Motorola has some LPC software on their bulletin board. Is there any other freely available speech-recognition software ? How about anything for speech generation or music generation ? I'm considering to build a scsi-connected DSP board to my pc532 machine and would like to make it handle incoming telephone messages with some voice/dtmf input and speech output capabilities. //Jyrki Jyrki Kuoppala Helsinki University of Technology, Finland.
